Pretty solid episode. Usually I dislike time travel episodes but this one worked given that it gave La'an opportunity for character development and the beginning of closure. I was a little worried that were edging back towards the temporal Cold War plot thread from Enterprise with the ending. Hopefully they will stay well clear of it.
One thing is the last 3 episodes in terms of content have felt like they belong in the back half of season 1. Not that it is bad thing, but there is the feeling that we are waiting for the season proper to kick off.
